In the present study using the wavelet theory (WT) and later the nonlinear spectrum response of the acceleration (NSRA) resulted in estimating a strong earthquake record for the structure to a degree of freedom. WT was used in order to estimate the acceleration of earthquake mapping with equal sampling method (WTESM). Therefore, at first, the acceleration recorded in an earthquake using WTESM w...

A small macroeconomic model is constructed starting from a German money demand relation for M3 based on quarterly, seasonally unadjusted data for the period from 1976 to 1996. In contrast to previous studies we build a vector error correction model for M3, GNP, an innation rate and an interest rate spread variable to represent opportunity costs of holding money. Furthermore, import price innati...

In researching the Helmholtz equation, focus has either been on accuracy of numerical solution (pollution) or acceleration convergence a preconditioned Krylov-based solver (scalability). While it is widely recognized that properties can be investigated by studying eigenvalues, information from eigenvalues not used in dispersion which drives pollution error. Our aim to bring topics and scalabili...

Abstract Background To evaluate early optical quality outcomes after small-incision lenticule extraction (SMILE) surgery for correcting high myopic astigmatism. Methods This retrospective study enrolled 55 eyes from 37 patients who had preoperative astigmatism of ≥2.00 diopters (D) been treated with SMILE surgery. Preoperatively, the mean cylinder was − 2.41 ± 0.54 D (range, 2.00 to 4.50 D). Th...

This paper proposes a new convergence acceleration method specialized for the magnetic field analyses of synchronous machines based on time-periodic explicit-error-correction (TP-EEC) method. The proposed constructs an auxiliary equation error correction in dq rotational reference frame to convert fundamental harmonic component into DC component. conversion enables us perform using TP-EEC at in...

Background: The current study aimed to evaluate the effects of barefoot and shod running with two different styles on ground reaction force-frequency content in recreational runners with low arched feet. Methods: The statistical sample of this research was 13 males with PF (mean±SD age: 26.2±2.8 y; height: 176.1±8.4 cm; weight: 78.3±14.3 kg). A force plate (Bertec, USA) with a sample rate of 1...
